After introducing the Rover SD1 Auto Efi Vdp and Auto Vitesse Rover started to receive reports of engine stalling when Drive was selected. To overcome this an Anti-stall modification was devised.
When the problem was confirmed on a customer’s car, the Anti-stall alteration was carried out at dealer level. Although the dealerships retained details of the change, no Anti-stall documentation ever appeared in the Rover SD1 Workshop Manuals.
About 1000 Rover SD1 Efi Vdp's were manufactured and perhaps a few dozen Rover SD1 Vitesse versions. Over time, as ownership of these vehicles changed, less dealership servicing was performed and knowledge of the alteration became lost, particularly for newer owners.
This essay is written to explain the whole curious story though it is unlikely there are many owners who may need the information it is a fascinating tale of Rover's approach to problem solving.
